How much will Loft Insulation cost & save me?

The amount you spend and save depends primarily on whether you currently have any insulation at all in your loft, and if you decide to install it yourself or leave it to a professional. If you have no loft insulation and you install the recommended 270mm depth you could save up to £180 a year on your heating bills and around 730kg of CO2 per year 1.

And remember, insulation is maintenance free. You will continue to enjoy the savings year after year. View the figures here
